The Book of Indian Shells by Deepak Apte, first published by the BNHS-OUP in 1999, and widely used as a field guide for many years, is now out of print and also outdated from the taxonomic point of view. Taxonomy is rapidly evolving, especially for lower taxa; several names have changed sinceThe Book of Indian Shells was published. Several species have been rearranged taxonomically or newly described. Sea Shells of India is an updated version of The Book of Indian Shells not just with regards to taxonomy, but also with respect to quality of illustrations. The book aims to aid studentsand researchers in field identification. It covers 488 species of gastropods in colour with comprehensive synonyms, besides 21 plates of live animals, allowing the reader to appreciate the beauty of the animals that reside inside these shells.
